二、5 Core Competitive Advantages
1.Outstanding Anti-Corrosion Performance：SS304/316L stainless steel flow channel withstand pH 1-14 corrosive media including acid, alkali, organic solvent. Service life far longer than ordinary cast iron pumps, suitable for harsh chemical working conditions.
2.Powerful Self-Priming Dry Start Function：Max self-priming height reaches 6.5 meters, fully finish suction within 30-90 seconds after startup. No bottom valve or vacuum auxiliary equipment required, simplify pipeline layout and reduce installation cost.
3.Ultra-Wide Medium Adaptability：Can transfer foamy gas-containing liquid, mild slurry with solid content ≤15%, liquid with tiny solid particles. Cover clean water, dairy, fruit juice, chemical solvent, acid alkali wastewater, oil-water mixture.
4.High Efficiency & Low Maintenance Cost：Hydraulic optimized impeller boosts efficiency to 55%-68%, cut power consumption by 20%-30%. Mechanical seal supports fast disassembly & replacement, detachable pump shell simplifies daily cleaning without pipeline removal.
5.Compact Safe & Stable Operation:30% lighter weight than traditional pumps, small footprint for limited installation space. Running noise <75dB with tiny vibration, explosion-proof motor option available for flammable chemical workshop.
